My 2 cents...I let the oil drain overnight. I also, a few times before going to bed, sit on the seat, grab the front brake, and bounce up and down on the seat while rocking left and right. Each time I do this I get another small but steady stream of oil for several minutes. EDIT: and I go Varooom...Varoom too! Now everyone knows my secrets.
EDIT: If your spending more $$ than the cost of Rotella, YOU'RE a FOOL!!!
